String theory is uniquely derived from basic assumptions about the universe, physicists show

Scientific Methodology Theoretical Physics String Theory

Researchers from Caltech, NYU, and the Institut de Fisica d'Altes Energies used a 'bootstrap' approach to derive the elements of string theory from basic assumptions about particle scattering. The study suggests that these assumptions lead uniquely to the hallmarks of string theory, though the authors note this is theoretical work rather than experimental evidence.

“In a new paper titled "Strings from Almost Nothing," accepted for publication in Physical Review Letters, Caltech researchers, and their colleagues at New York University and Institut de Fisica d'Altes Energies in Barcelona, have [derived the elements of string theory from a couple of basic assumptions about how particles should scatter off one another at very high energies].”
